  • Earn your completion certificate in Horse Genetics!

This 3-part extension course has as focus to enable the access to equine genetics knowledge to any person who may be interested in the subject. Although some prior knowledge in basic genetics is appreciated, it's not essential for the understanding or conclusion of this course. 

At the conclusion of this course students will have the ability to:

  • Use the principles of inheritance to predict phenotype, based on genotype.
  • Evaluate pedigree records for genetic health as well as marketability.
  • Describe the symptoms and implications of genetic disease in the horse.
  • Understand the complexity of genetic diversity, breeds and registries.
  • Advantageously utilize available genetic tests to plan a breeding program. 

This equine genetics course is 100% online, with weekly modules that can be fulfilled according to the student's personal time schedule. At each week, a new subject in the equine genetics will be approached. In each module, the student will find pages with suggested reading and instructions, narrated slideshows, comprehension tests and activities. The subjects covered in this course will go from basic mendelian genetics, equine genome, coat color and patterns of white, parentage testing, genetic diseases, gait and other subjects of common interest.

Horse Genetics 1 - Online


The art of horse breeding has shaped equine genetics since domestication, yet most horse professionals have little understanding of the fundamentals of genetics. In this first installment of a three part series of short courses, we will examine the underlying mechanisms and inheritance of a number of single gene traits, ways that these patterns can be used to improve the management and marketability of horses, and how horse owners access testing.

Dr. Samantha Brooks

A lifelong horse woman, Dr. Samantha Brooks was diverted from vet school by a budding passion for equine research. Following a Bachelor of Science degree in Agricultural Biotechnology, Dr. Brooks remained at the University of Kentucky to study at the Gluck Equine Research Center. While there she earned her PhD in Veterinary Science, specializing in Equine Genetics under the mentorship of Dr. Ernest Bailey. Following her PhD she was awarded the Paul Mellon Postdoctoral Fellowship to study the expression of inflammatory genes in horses affected with laminitis. At Cornell University she was responsible for the Equine Biology and Management course for six years. Her research program explores a variety of topics relevant to horse health ranging from gene expression studies to mapping of genetic disorders in the horse. Previously her research group discovered genetic mutations and markers for coat colors, height, sarcoid tumors and two neurological conditions.  Ongoing work targets variation in gait, susceptibility to infectious disease, metabolic syndrome and skeletal defects using genome wide association, genome re-sequencing and transcriptomics.
